IMPROVEMENT 1N PESSARIES.

J. I). WILLMS, 0F BALTIMORE, MARYLAND. Letters Patent Nb.A 6(-),312, dated .Decemberl 4, 1866.

SPECIFICATION. T0 ALL WHOM IT MAY CONCERN Be it known that I, JonN PETER WILLMs, of the city and county of Baltimore, and State of Maryland, have invented a new and improved Pessary; and I do hereby declare the following to be a full, clear, and exact description of the same, sufficient to enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Fignre 1 is a view of the instrument with the lobes collapsed, aud the stem uncovered.

Figure 2 is a view with the lobes partially expanded, and the stom covered with a sleeve for the protection of the working parts. d 4 Figure 3 is a view of a single detached lobe.

Figure 4 is a view of the stem and hinges, the lobes being removed and hinge expanded.

Figure 5 is a view of the stem and hinge, the lobes removed and the hinge collapsed.

The lobes are hinged at the end of the stem, and are so arranged and constructed as to collapse while being introduced into the vagina; vthey open forward, (relatively to the pcrson,) the lobes and stem permitting the free discharge of the secretions; the machinery being within and upon the stem, aud covered by a sleeve of non-absorbent material the lobes are uncovered and made of single pieces of hard rubber, ivory, or analagous material, and are unencumbered by the interposition between them of any part of the machinery whose presence would limit their motions, andwhose protection would linvolve interference with the discharge of the secretions,

`and possibly necessitate the covering of the 4lobes and machinery in a commoneasing.

In the drawings, A A are the lobes, joined by the plates F, and hinge b; the'lobes are made of single annular pieces of' ivory, hard rubber, or analogous material, and are opened by means of the rotation of the handle I), whose threaded portion E is swiveled into the end of the stem C, which isattached to the hinge et the lobes. The screw E, as the handle D is rotated, moves in the nut at the junction of the arms B, to whose ends the plates F are so pivoted that, as the stein C is projected or withdrawn, opening or closing the lobes, the latter vibrate upon the sockets on the ends of the arms, which limit their outward motion. The plates F are imbedded inthe material of the lobes, and secured by rivets; those portions of the `apparatus between the hinge and thehandle D are covered and protected by a sleeve, Grot rubber or other non-absorbent elastic material. .And the machinery, by being embraced within the space between the hinge and the handle, in no case becomes a barrier to the collapse of the lobes, and is covered by a sleeve of moderate size, which does not prevent the discharge of the secretions, and permits the lobes, thus Clear of encumbrance, to be made of single pieces'ol hard rubber, o1' ivory, which will not retain impurities, admit of being most readily and thoroughly cleansed, and cannot ex crt any deleterious inuence upon the parts bearing upon them.

The nature of the motion of my apparatus is, to thrust the joining portion of the lobes backward and against the uterus, while the lobes expand forwardly, (relatively to the person,) a motion new in itself, and involving substantial differences of construction from any others with which I am acquainted.

Having described my invention, what I claim as new, and desire to 'secure by Letters Patent, is

The lobes A, opening forwardly, relatively to the person, and operated by a swiveled screw and stem between thearms B, substantially as described and represented.
